Answer:
(e) the mean number of siblings for a large number of students has a distribution that is close to Normal.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
By the Central Limit Theorem
The sampling distributions with a large number of students(at least 30) will be approximately normal, so the correct answer is given by option e.
Answer:
Use an ruler if you must listen to explanation.
Step-by-step explanation:
So this is actually very easy so it already tells you the Width= Feet is 80. But the Length = Feet is 6 greater any time you see something that says Number? Greater it means Multiply so multiply 6x80=480 so your length will be 480 Ok that's true But! The Width isn't answered your paper/screen Says, The perimeter of a rectangular outdoor patio is 80 ft. The length is 6 feet greater than the width what are the dimersions of the patio. Dimersion's what is it? The number.
So your confused?
Here are a list of things you can use,
A ruler
A protractor
Or A Tape Measuerer
Pardon if spelled wrong.
Anyway the perimeter is 80 ft. Here's what i would do i would use a ruler and see how long the width is then times that with 6 and you should get your answer i cannot use my ruler because picture is to small even when clicked this should help you.
Hope this helped!
Answer:
p(chocolate chip) = 2/7
p(oatmeal) = 7/27
Step-by-step explanation:
probability = favorable outcomes/total outcomes
First, add up all the cookies in the bag.
8 + 6 + 7 + 7 = 28
Next find the probability of selecting a chocolate chip cookie. Since there are 8 chocolate chip cookies and 28 cookies in the bag, create a fraction.
p(chocolate chip) = 8/28
reduce by 4
p(chocolate chip) = 2/7
Now that the cookie was eaten that will reduce the number of chocolate chip cookies to 7 and the overall number of cookies to 27.
There are 7 oatmeal cookies and 27 total cookies, so create the fraction.
p(oatmeal) = 7/27
